Hereinafter, embodiments of the present disclosure will be described indetail with reference to the accompanying drawings. In adding referencenumerals to elements in each drawing, the same elements will bedesignated by the same reference numerals, if possible, although theyare shown in different drawings. Further, in the following descriptionof the present disclosure, a detailed description of known functions andconfigurations incorporated herein will be omitted when it is determinedthat the description may make the subject matter of the presentdisclosure rather unclear.

In the present disclosure, a wireless communication system refers to asystem for providing various communication services such as a voicecommunication service, a packet data service, etc. The wirelesscommunication system includes user equipment (UE) and a base station(BS).

The UE is a generic term referring to devices used in wirelesscommunication. For example, the UE may be referred to, but not limitedto, a UE supporting wideband code division multiple access (WCDMA), longterm evolution (LTE), high speed packet access (HSPA), internationalmobile telecommunications (IMT)-2020 (5G or new radio), or the like, amobile station (MS) supporting the global system for mobilecommunication (GSM), a user terminal (UT), a subscriber station (SS), awireless device, or the like.

The base station or a cell generally refers to a station communicatingwith the UE. The base station or cell is a generic term referring to,but not limited to, all of various communication service areas anddevices, such as a Node-B, an evolved Node-B (eNB), a gNode-B (gNB), alow power node (LPN), a sector, a site, various types of antennas, abase transceiver system (BTS), an access point, a point (e.g., atransmitting point, a receiving point, or a transceiving point), a relaynode, a megacell, a macrocell, a microcell, a picocell, a femtocell, aremote radio head (RRH), a radio unit (RU), and a small cell.

Each of the various cells is controlled by a base station. Therefore,the base station may be classified into two categories. 1) The basestation may be referred to an apparatus that forms a correspondingcommunication service area, such as a megacell, a macrocell, amicrocell, a picocell, a femtocell, and a small cell, and provides acommunication service within the corresponding communication servicearea, or 2) the base station may be referred to a communication servicearea. In the case of 1), the base station may be referred to i)apparatuses that are controlled by the same entity by forming anycorresponding communication service area and providing a communicationservice within the corresponding communication service, or ii) apparatusthat interact and cooperate with each other for forming a correspondingcommunication service area and providing a communication service withinthe corresponding communication service area. According to communicationschemes employed by a base station, the base station may be referred toas a point, a transmission/reception point, a transmission point, areception point, or the like. In case of 2), the base station may be acommunication service area itself where UEs able to receive signals fromor transmit signals to other UEs and neighboring base stations.

In the present disclosure, the cell may also refer to a coverage of asignal transmitted from a transmission/reception point, a componentcarrier having the coverage of a signal transmitted from a transmissionpoint or a transmission/reception point, or a transmission/receptionpoint itself.

The UE and the base station are two entities for performingtransmission/reception used to embody the technology and technicalspirit described in the present specification. The UE and the basestation are a generic term and not limited to specific terms or words.

Herein, the uplink (hereinafter, referred to as “UL”) refers to datatransmission/reception by a UE to/from a base station, and the downlink(hereinafter, referred to as “DL”) refers to data transmission/receptionby a base station to/from a UE.

UL transmission and DL transmission may be performed by employing i) atime division duplex (TDD) technique performing transmission throughdifferent time slots, ii) a frequency division duplex (FDD) techniqueperforming transmission through different frequencies, or iii) a hybridtechnique of the frequency division duplex (FDD) and the time divisionduplex (TDD).

Further, the related standard of the wireless communication systemdefines configuring the UL and the DL based on a single carrier or apair of carriers.

The UL and the DL transmit control information through one or morecontrol channels, such as a physical DL control channel (PDCCH), aphysical UL control channel (PUCCH), and the like. The UL and DLtransmit data through data channels, such as a physical DL sharedchannel (PDSCH), a physical UL shared channel (PUSCH), and the like.

The DL may denote communication or a communication path from multipletransmission/reception points to a UE, and the UL may denotecommunication or a communication path from the UE to the multipletransmission/reception points. In the DL, a transmitter may be a part ofmultiple transmission/reception points, and a receiver may be a part ofa UE. In the UL, a transmitter may be a part of a UE and a receiver maybe a part of multiple transmission/reception points.

Hereinafter, transmission and reception of a signal through a channelsuch as the PUCCH, the PUSCH, the PDCCH, or the PDSCH, may be describedas the transmission and reception of the channel, such as the PUCCH, thePUSCH, the PDCCH, or the PDSCH.

Meanwhile, higher layer signaling includes radio resource control (RRC)signaling transmitting RRC information containing an RRC parameter.

The base station performs DL transmission to UEs. The base station maytransmit a physical DL control channel for transmitting i) DL controlinformation, such as scheduling required to receive a DL data channelthat is a primary physical channel for unicast transmission, and ii)scheduling approval information for transmission through an UL datachannel. Hereinafter, transmitting/receiving a signal through eachchannel may be described in such a manner that a corresponding channelis transmitted/received.

Any of multiple access techniques may be applied to the wirelesscommunication system, and therefore no limitation is imposed on them.For example, the wireless communication system may employ variousmultiple access techniques, such as time division multiple access(TDMA), frequency division multiple access (FDMA), CDMA, orthogonalfrequency division multiple access (OFDMA), non-orthogonal multipleaccess (NOMA), OFDM-TDMA, OFDM-FDMA, OFDM-CDMA, or the like. The NOMAincludes sparse code multiple access (SCMA), low cost spreading (LDS),and the like.

Embodiments of the present disclosure may be applied to resourceallocation in asynchronous wireless communication evolving intoLTE/LTE-advanced and IMT-2020 from GSM, WCDMA, and HSPA, synchronouswireless communication evolving into CDMA, CDMA-2000, and UMB.

In the present disclosure, a machine type communication (MTC) terminalmay refer to a terminal supporting low costs (or low complexity), aterminal supporting coverage enhancement, or the like. As anotherexample, the MTC terminal may refer to a terminal defined as apredetermined category for supporting low cost (or low complexity)and/or coverage enhancement.

In other words, the MTC terminal may refer to a low cost (or lowcomplexity) user equipment category/type newly defined in 3GPPRelease-13 and performing LTE-based MTC-related operations. The MTCdevice of the present disclosure may refer to a device category/typethat is defined in or before 3GPP Release-12 that supports enhancedcoverage in comparison with the existing LTE coverage or supports lowpower consumption, or may refer to a low cost (or low complexity) devicecategory/type newly defined in Release-13. The MTC terminal may refer toa further enhanced MTC terminal defined in Release-14.

In the present disclosure, a narrowband Internet of Things (NB-IoT)terminal refers to a terminal supporting radio access for cellular IoT.NB-IoT technology aims to improve an indoor coverage, to support forlarge-scale low-speed terminals, to lower latency sensitivity, to reduceterminal costs, to lower power consumption, and to optimize a networkarchitecture.

An enhanced mobile broadband (eMBB), massive machine-type communication(mMTC), and ultra-reliable and low latency communication (URLLC) areproposed as representative usage scenarios for NR having been discussedin the 3GPP recently.

In the present disclosure, a frequency, a frame, a subframe, a resource,a resource block (RB), a region, a band, a sub-band, a control channel,a data channel, a synchronization signal, various reference signals,various signals, and various messages, associated with NR may beinterpreted as meanings that were used in the past or are used in thepresent or as various meanings that will be used in the future.

Meanwhile, in the present disclosure, an uplink control channel definedfor UCI transmission/reception corresponding to a PUCCH in the LTE isdescribed as an NR PUCCH, but the embodiments of the present disclosureare not limited thereto.

NR (New Radio)

Recently, the 3GPP has approved the “Study on New Radio AccessTechnology”, which is a study item for research on next-generation/5Gradio access technology. On the basis of the Study on New Radio AccessTechnology, discussions have been in progress for frame structures,channel coding and modulation, waveforms, multiple access methods, andthe like for the new radio (NR).

The NR is required to be designed not only to improve a datatransmission rate as compared with the long term evolution(LTE)/LTE-Advanced, but also to meet various requirements per detailedand specific usage scenario. An enhanced mobile broadband (eMBB),massive machine-type communication (mMTC), and ultra-reliable and lowlatency communication (URLLC) are proposed as representative usagescenarios of the NR. In order to meet the requirements per usagescenario, it is required for designing the NR to have flexible framestructures, compared with the LTE/LTE-Advanced.

Specifically, the eMBB, mMTC, URLLC are considered as representativeusage scenarios of the NR by the 3GPP. Since each usage scenario imposesdifferent requirements for data rates, latency, coverage, etc., therearises a need for a method of efficiently multiplexing numerology-based(e.g., a subcarrier spacing (SCS), a subframe, a transmission timeinterval (TTI), etc.) radio resource units different from each other, asa solution for efficiently satisfying requirements according to usagescenarios through a frequency band provided to an arbitrary NR system.

To this end, there have been discussions on i) methods of multiplexingnumerologies having subcarrier spacing (SCS) values different from oneanother based on TDM, FDM or TDM/FDM through one NR carrier, and ii)methods of supporting one or more time units in configuring a schedulingunit in the time domain. In this regard, in the NR, a definition of asubframe has been given as one type of a time domain structure. Inaddition, as a reference numerology to define a corresponding subframeduration, a single subframe duration is defined as having 14 OFDMsymbols of normal CP overhead based on 15 kHz subcarrier spacing (SCS),like the LTE. Therefore, the subframe of the NR has the time duration of1 ms. Unlike the LTE, since the subframe of the NR is an absolutereference time duration, a slot and a mini-slot may be defined as a timeunit for actual UL/DL data scheduling. In this case, the number of OFDMsymbols which constitutes a slot, a value of y, has been defined as y=14regardless of the numerology.

Therefore, a slot may be made up of 14 symbols. In accordance with atransmission direction for a corresponding slot, all symbols may be usedfor DL transmission or UL transmission, or the symbols may be used inthe configuration of a DL portion+a gap+a UL portion.

An UL Control Channel for a Next Generation Radio Access Network

An UL control channel is required for enabling a UE to transmit controlinformation to a base station. As described above, it is noted that inthe NR, a flexible channel structure is required for satisfying variousservice scenarios. In consideration of such circumstances, an UL controlchannel for transmitting/receiving UL control information (UCI) in theNR may contain one or more symbols therein. For example, as shown inFIG. 1 to 3, the UL control channel may be configured with one or moresymbols.

FIG. 1 is a diagram illustrating an UL control channel configured withone symbol according to embodiments of the present disclosure. FIG. 2 isa diagram illustrating an UL control channel configured with two symbolsaccording to embodiments of the present disclosure.

For example, as shown in FIG. 1, an NR PUCCH may be configured to have ashort duration for enabling the UCI which is transmitted/receivedthrough one UL symbol. That is, the UL control channel may be configuredwith one symbol, and this may be transmitted through an UL controlregion. In frequency domain, the UL control channel may be configureddepending on configurations. A plurality of UL control channel sets maybe configured, and a UE may selectively use one or more of the ULcontrol channel sets according to an indication of a base station.

For another example, as shown in FIG. 2, an NR PUCCH may be configuredwith two symbols. In this case, in frequency domain, the UL controlchannel may be configured depending on configurations. A plurality of ULcontrol channel sets may be configured, and a UE may selectively use oneor more of the UL control channel sets according to an indication of abase station.

An UL control channel configured with the number of UL control channelsymbols (one or two) shown in FIGS. 1 and 2 is described and discussedas a short PUCCH. The short PUCCH is merely for distinguishing from along PUCCH which is an UL control channel configured with four or moresymbols. However, embodiments of the present disclosure are not limitedto these terms.

FIG. 3 is a diagram illustrating an UL control channel configured withsix symbols according to embodiments of the present disclosure.

Referring to FIG. 3, an NR PUCCH may be configured with a plurality ofsymbols (e.g., the number of symbols greater than and equal to apre-configured number of symbols). For example, the NR PUCCH may beconfigured with six symbols. Alternatively, the number of symbols may bedetermined as a natural number greater than or equal to two or four.

That is, the NR PUCCH may be classified into the short PUCCH configuredwith one or two symbols and the long PUCCH configured with four or moresymbols. The PUCCH may also be classified based on PUCCH formats.

Meanwhile, in the NR, the UL control channel may support the followingtwo types of transmission.

For one example, the UL control channel may be transmitted through theshort PUCCH in one or more last UL symbols transmitted in one symbol. Inthis case, an UL data channel in one symbol may be processed in an FDMmethod and/or a TDM method. To this end, it is necessary to provide atechnology for processing a potential gap at the end portion of acorresponding slot. For another example, the UL control channel may betransmitted through another symbol (e.g., one or more symbols at thebeginning portion of one slot). For further another example, the ULcontrol channel may be transmitted through the long PUCCH by multiple ULsymbols for enhanced coverage. In this case, an UL data channel in onesymbol may be processed in the FDM method. However, a technology isfurther required for the multiplexing of a sounding reference signal(SRS).

Meanwhile, in case frequency hopping is applied, the frequency hoppingis not performed beyond a carrier bandwidth. In addition, in frequencydomain, one or multiple physical resource blocks (PRB) may be a size ofa minimum resource unit for the UL control channel. In addition, aUE-specific reference signal may be used for transmitting UL controlchannel.

As described above, in accordance with embodiments of the presentdisclosure, a method of a UE and a device are provided for transmittingUL control information through a UL control channel in a next generationradio access network for satisfying requirements of various servicescenarios. For example, two types (or formats) of NR PUCCH each having adifferent duration from the other are defined in time domain, and, foreach type, a method for configuring one or more UL control channelresources, and a specific transmission method are discussed according toembodiments.

Hereinafter, for convenience of description and ease of understanding,an NR PUCCH having a long duration, i.e. configured with four or moresymbols, is referred to as a long PUCCH format and an NR PUCCH having ashort duration is referred to as a short PUCCH format. The embodimentsof the present disclosure are not limited to the terms, and variousPUCCH formats may be defined. For example, it is possible to define aplurality of PUCCH formats having a short duration and a plurality ofPUCCH formats having a long duration.

In addition, the PUCCH format may be also classified based on a payloadsize of the UL control information. For example, a plurality ofdifferent PUCCH formats from one another may be configured based on apayload size of UL control information for each duration. That is, inconfiguring the NR PUCCH format, along with the classification (longPUCCH and short PUCCH) according to the PUCCH duration, the PUCCH formatmay be configured according to the UCI payload size to be transmitted bya UE through each PUCCH.

Hereinafter, the PUCCH format will be described for each of the longPUCCH and the short PUCCH classified according to the duration. Asdescribed above, the PUCCH format may be further classified by an UCIpayload size.

Thus, a method is provided for allocating resources for each PUCCHformat in an NR subframe, a slot, or a mini-slot when two NR PUCCHformats are defined based on different time durations. In addition, amethod is provided for configuring an NR PUCCH format for transmitting acorresponding UCI when a UE transmits a UCI (e.g., hybrid automaticrepeat request (HARQ) ACK/NACK, channel state information (CSI),scheduling request (SR) etc.) in the NR subframe, the slot, or themini-slot. Accordingly, methods are provided i) for configuring one ormore NR PUCCH resources for each format and ii) for transmitting UCI foreach NR UE, in the NR subframe, the slot, or the mini-slot.

FIG. 4 is a diagram illustrating an UL control channel configured usinga DL control channel according to embodiments of the present disclosure.

Referring to FIG. 4, a PUCCH resource set may be configured for a UE.When the UE transmits UL control information, the UE may transmit theinformation to a base station through a PUCCH which is scheduled by aPDCCH. In this case, the UE may transmit the UL control information tothe base station using one of PUCCH resource sets indicated by thePDCCH. To this end, the UE may receive PUCCH resource set configurationinformation from the base station.

In the present disclosure, UL control region configuration informationmay have the same meaning of PUCCH resource set configurationinformation. That is, the UL control region configuration informationand the PUCCH resource set configuration information mean information onone or more PUCCH resources needed for enabling a UE to transmit an ULcontrol channel which is received from a base station. Accordingly, anUL control channel resource set and an UL control region may beidentical in meaning.

FIG. 5 is a flowchart illustrating operation of a UE according toembodiments of the present disclosure.

Referring to FIG. 5, the UE may perform operations for receiving, from abase station, at least one of an UL control channel resource setconfiguration information and UL control channel transmissioninformation at step S510.

For example, the UL control channel resource set configurationinformation may include at least one of UL control channel transmissiontype setting information and frequency resource allocation informationof an UL control channel. The UL control channel transmission typesetting information may include information on whether frequency hoppingis performed for each UL control channel format and may be classifiedinto a localized type and a distributed type. The localized transmissiontype means UL control information transmission through one or moreconsecutive localized PRB s on which frequency hopping is not performed.The distributed transmission type means UL control informationtransmission through frequency hopping applied on a symbol or a symbolgroup basis. In addition, the frequency resource allocation informationof the UL control channel may include at least one of UL control channelformat information and PRB allocation information for each UL controlchannel format.

For another example, the UL control channel transmission information mayinclude at least one of UL control channel format information, ULcontrol channel transmission type information, and priority informationfor each UL control channel format, configured for each UE. The ULcontrol channel format information means information on a PUCCH formatincluding the long PUCCH and the short PUCCH. The UL control channeltransmission type information may mean information for indicating whichof the distributed type and the localized type is applied. Further, thepriority information for each UL control channel format meansinformation for determining a format having a top priority which can beused when a UE transmits UL control information, in case both the longPUCCH and the short PUCCH are configured for the UE. The UE may transmitUL control information using a PUCCH format having a top priority.

Meanwhile, the UL control channel resource set configuration informationmay be received in advance for enabling the UE to transmit an UL controlchannel. For example, the UL control channel resource set configurationinformation may be received through at least one of cell-specific highlayer signaling, UE-specific high layer signaling, and a common searchspace of a DL control channel. The UE may recognize radio resourceinformation for enabling the UE to transmit UL control information usingthe received UL control channel resource set configuration information.The UL control channel resource set configuration information may beconfigured cell-specifically and received by the UE.

The UL control channel transmission information may be received togetherwith or separately from the UL control channel resource setconfiguration information. The UL control channel transmissioninformation may be received through the UE-specific high layer signalingor the common search space of the DL control channel. That is, the ULcontrol channel transmission information may be configuredUE-specifically and received by the UE.

Through such a manner, the UE may recognize information on a controlregion for transmitting an UL control channel, and a PUCCH format, atransmission type, priority information, and the like, configured forthe UE.

The UE may perform operations for configuring an UL control channelincluding UL control information based on at least one of the UL controlchannel resource set configuration information and the UL controlchannel transmission information at step S520. For example, when the UEis required to transmit UL control information to a base station, the UEmay configure an UL control channel for transmitting the UL controlinformation using the information received in the step S510.

For one example, the UE may transmit the UL control information using aPUCCH format configured for the UE in an allocated UL control region.

For another example, when an UL control region for an UL control channelformat configured for the UE is not allocated, the UE may configure anUL control channel through an UL control region for another UL controlchannel format having a resource index identical to an UL controlchannel resource index based on the set UL control channel format. Forexample, an UL control region configured with four or more symbols fortransmitting an UL control channel using the long PUCCH format may notbe allocated even when the long PUCCH format is set for the UE. In thiscase, the UE may configure an UL control channel using an UL controlregion for the short PUCCH format having a resource index identical toan UL control channel resource index for transmitting an UL controlchannel using the long PUCCH format.

For another example, the UE may configure the UL control channel usingan UL control channel format having a top priority based on priorityinformation for each UL control channel format. When an UL controlregion for the UL control channel format having the top priority is notallocated, the UE may configure the UL control channel using an ULcontrol channel format having a second priority. For example, the UE maydetermine an UL control channel format and configure the UL controlchannel depending on a priority set for the UE using priorityinformation for each UL control channel format.

Meanwhile, as described above, the UL control channel may be classifiedinto one or more formats based on the number of symbols contained in theUL control channel, as one criterion. For one example, i) an UL controlchannel configured with one symbol or two symbols and ii) an UL controlchannel configured with four or more symbols may be each configured witha different format from the other. For another example, the UL controlchannel format may be classified into based on a payload size of ULcontrol information, as another criterion. That is, the UL controlchannel format may include i) a format configured with two or less ULcontrol channel transmission symbols and ii) a format configured withfour or more UL control channel transmission symbols, transmittedthrough a single slot, or may be classified into based on a payload sizeof UL control information.

The UE may perform operations for transmitting the UL control channel tothe base station at step S530. The UE may transmit the UL controlinformation through the configured UL control channel.

Through such operations, the UE may receive information on the ULcontrol region (UL control channel resource set) and the UL controlchannel, and transmit the UL control information to the base station.Thus, the UE can satisfy requirements of each service using various ULcontrol channel formats.

FIG. 6 is a flowchart illustrating operation of a base station accordingto embodiments of the present disclosure.

Referring to FIG. 6, the base station may perform operations forconfiguring at least one of i) UL control channel resource setconfiguration information and ii) UL control channel transmissioninformation, for a UE at step S610. The base station may configureinformation for enabling the UE to transmit an UL control channel.

For example, the UL control channel resource set configurationinformation may include at least one of UL control channel transmissiontype setting information and frequency resource allocation informationof the UL control channel. The UL control channel transmission typesetting information may include information on whether frequency hoppingis performed for each UL control channel format, or the UL controlchannel transmission type setting information may be classified into alocalized type and a distributed type. The localized transmission typemeans UL control information transmission through one or moreconsecutive localized PRBs on which frequency hopping is not performed.The distributed transmission type means UL control informationtransmission through frequency hopping applied on a symbol or a symbolgroup basis. In addition, the frequency resource allocation informationof the UL control channel may include at least one of UL control channelformat information and PRB allocation information for each UL controlchannel format.

For another example, the UL control channel transmission information mayinclude at least one of UL control channel format information, ULcontrol channel transmission type information, and priority informationfor each UL control channel format, configured for each UE. The ULcontrol channel format information means information on a PUCCH formatincluding the long PUCCH and the short PUCCH. The UL control channeltransmission type information may mean information for indicating whichof the distributed type and the localized type is applied. Further, thepriority information for each UL control channel format meansinformation for determining a format having a top priority which can beused when a UE transmits UL control information, in case both the longPUCCH and the short PUCCH are configured for the UE. The UE may transmitUL control information using a PUCCH format with a top priority.

The base station may perform operations for transmitting at least one ofthe UL control channel resource set configuration information and the ULcontrol channel transmission information at step S620.

For example, the UL control channel resource set configurationinformation may be transmitted in advance for enabling the UE totransmit an UL control channel. For example, the UL control channelresource set configuration information may be transmitted through atleast one of cell-specific high layer signaling, UE-specific high layersignaling, and a common search space of a DL control channel. The UE mayrecognize radio resource information for enabling the UE to transmit ULcontrol information using the received UL control channel resource setconfiguration information. The UL control channel resource setconfiguration information may be configured cell-specifically andtransmitted to the UE.

For another example, the UL control channel transmission information maybe transmitted together with or separately from the UL control channelresource set configuration information. The UL control channeltransmission information may be transmitted through the UE-specific highlayer signaling or the common search space of the DL control channel.That is, the UL control channel transmission information may beconfigured UE-specifically and transmitted to the UE.

Through such a manner, the UE may recognize information on a controlregion (UL control channel resource set) for transmitting an UL controlchannel, and a PUCCH format, a transmission type, priority information,and the like, configured for the UE.

The base station may perform operations for receiving an UL controlchannel including UL control information based on at least one of the ULcontrol channel resource set configuration information and the ULcontrol channel transmission information at step S630. For example, whenthe UE is required to transmit the UL control information to a basestation, the UE may configure the UL control channel for transmittingthe UL control information using the information received in the stepS620.

For one example, the UE may transmit the UL control information using aPUCCH format configured for the UE in an allocated UL control region,and then the base station may receive this.

For another example, when an UL control region for an UL control channelformat configured for the UE is not allocated, the UE may configure anUL control channel through an UL control region for another UL controlchannel format having a resource index identical to an UL controlchannel resource index based on the set UL control channel format. Forexample, an UL control region configured with four or more symbols fortransmitting an UL control channel using the long PUCCH format may notbe allocated even when the long PUCCH format is set for the UE. In thiscase, the UE may configure the UL control channel using an UL controlregion for the short PUCCH format having a resource index identical toan UL control channel resource index for transmitting an UL controlchannel using the long PUCCH format.

For another example, the UE may configure the UL control channel usingan UL control channel format having a top priority based on priorityinformation for each UL control channel format. When an UL controlregion for the UL control channel format having the top priority is notallocated, the UE may configure the UL control channel using an ULcontrol channel format having a second priority. For example, the UE maydetermine an UL control channel format and configure an UL controlchannel depending on a priority set for the UE using priorityinformation for each UL control channel format.

Meanwhile, as described above, the UL control channel may be classifiedinto one or more formats based on the number of symbols contained in theUL control channel, as one criterion. For one example, each of an ULcontrol channel configured with one symbol or two symbols and an ULcontrol channel configured with four or more symbols may be configuredwith a different format from the other. For another example, the ULcontrol channel format may be classified into based on a payload size ofUL control information, as another reference. That is, the UL controlchannel format may include a format configured with two or less ULcontrol channel transmission symbols and a format configured with fouror more UL control channel transmission symbols, transmitted through asingle slot, or may be classified into based on a payload size of ULcontrol information.

The base station may receive, through a corresponding channel, the ULcontrol information which is transmitted by the UE through the ULcontrol channel configured using the method described above.

Hereinafter, embodiments of configuring an UL control region describedabove and embodiments of transmitting UL control information by each UEthrough the UL control region will be discussed in detail.

Hereinafter, UL control channel resource set configuration informationmay be referred to as UL control region configuration information as ameaning of configuration information for a resource region transmittingan UL control channel. Accordingly, it should be considered that the ULcontrol channel resource set configuration information below isinterpreted into the same meaning as the UL control channel resource setconfiguration information described above.

An Embodiment of Resource Allocation for Configuring an UL ControlRegion

An NR cell/base station may establish an UL control region fortransmitting UCI of a UE in the corresponding cell and may explicitlysignal UL control region configuration information (the UL controlchannel resource set configuration information described above) for UEsin the cell. In this case, the UL control region configurationinformation may include at least one of i) transmission type settinginformation and ii) frequency resource allocation information, for eachNR PUCCH format.

For example, in an NR system, in addition to the long PUCCH format andthe short PUCCH format which are classified based on the time durationdescribed above, each NR PUCCH format may be classified into a) alocalized transmission type for maximizing a frequency selectivescheduling gain and b) a distributed transmission type for maximizing afrequency diversity gain. The localized transmission type in each of thelong PUCCH format and the short PUCCH format may be an NR PUCCHtransmission type for performing UCI transmission through one or moreconsecutive localized PRBs on which frequency hopping is not performed.The distributed transmission type may be an NR PUCCH transmission typeto which frequency hopping is applied on a per-symbol or a per-symbolgroup basis, or an NR PUCCH transmission type for performing UCItransmission through distributed PRBs.

It should be considered that, in defining the PUCCH transmission type,each of the long PUCCH format and the short PUCCH format may be set toboth the localized transmission type and the distributed transmissiontype, and, as described above, the corresponding transmission typesetting information may be included in UL control region configurationinformation for each NR PUCCH format.

Alternatively, the transmission type may be defined and set only for aspecific PUCCH format. For example, the long PUCCH format may always beset to only the distributed transmission type through frequency hopping(or distributed PRBs), and the short PUCCH format may be set to eitherthe localized transmission type or the distributed transmission type bya base station. On the contrary, the long PUCCH format may be set toeither the localized transmission type or the distributed transmissiontype, and the short PUCCH format may be set to either the localizedtransmission type or the distributed transmission type, as a defaultvalue.

Meanwhile, the UL control region configuration information may includefrequency resource allocation information. The frequency resourceallocation information may be PRB allocation information for each NRPUCCH format.

In addition, the UL control region configuration information for eachPUCCH format may be semi-statically configured and transmitted throughcell-specific high layer signaling or UE-specific high layer signaling.Alternatively, the UL control region configuration information may bedynamically configured and transmitted through a DL L1/L2 controlchannel. In this case, in case dynamic allocation method through theL1/L2 control channel is applied, the UL control region configurationinformation may be configured and transmitted based on a unit of a radioframe, a subframe, or slot/mini-slot through a common search space of anNR PDCCH defined for each numerology or numerology specifically.

Through such a method, the UE may receive control region configurationinformation for transmitting an UL control channel.

An Embodiment of Transmitting UL Control Information for Each UE

An NR PUCCH format for transmitting UCI of the long PUCCH format or theshort PUCCH format may be set for transmitting the UCI through asubframe, a slot, or a mini-slot for each UE. Further, a transmissiontype setting may be performed for a PUCCH format set additionally. Inthis case, the corresponding setting may be configured semi-staticallythrough UE-specific higher layer signaling or configured dynamicallythrough a L1/L2 control channel, for each UE.

Thus, when a UE is able to set an NR PUCCH format and a transmissiontype for transmitting UCI, an UL control region based on the PUCCHformat may not be configured in a subframe, slot, or mini-slotconfigured for enabling the UE to transmit any UCI (e.g., HARQ ACK/NACK,CSI, SR etc.). For example, UL control region allocation based on thelong PUCCH format may not performed by a base station in an UL slot fora UE configured to transmit HARQ ACK/NACK feedback information based onthe long PUCCH format through the UL slot.

For one example, in case of not performing UL control region allocationbased on a PUCCH format set for a UE in a time-domain unit (e.g., asubframe, a slot, or a mini-slot) configured to transmit any UCI in theUE, the UE may delay UL control information and transmit it through afirst subsequent time-domain unit after the UL control region allocationbased on the PUCCH format set for the UE has been performed.

For another example, in case of not allocating the UL control region,the UE may not transmit the UL control information and drop it.

For further another example, in case of i) not performing UL controlregion allocation based on a PUCCH format set for a UE in a time-domainunit (e.g., a subframe, a slot, or a mini-slot) configured to enable theUE to transmit any UCI, but ii) performing UL control region allocationbased on one or more other PUCCH formats, the UE may transmitcorresponding UCI through a PUCCH resource having an identical resourceindex of UL control regions based on the one or more other PUCCHformats. More specifically, for a UE configured to transmit HARQACK/NACK feedback information based on the long PUCCH format, when an ULcontrol region based on the long PUCCH format in a subframe for enablingthe UE to transmit the HARQ ACK/NACK feedback information is notconfigured, but when an UL control region based on the short PUCCHformat has been configured, the UE may transmit the HARQ ACK/NACKfeedback information based on the short PUCCH format. That is, the UEmay transmit the HARQ ACK/NACK feedback through a short PUCCH resourcehaving a resource index identical to a PUCCH resource index based on thelong PUCCH format allocated for the HARQ ACK/NACK feedback of the UE.

Meanwhile, each UE may configure i) UL control information configurationinformation based on the long PUCCH format and ii) UL controlinformation configuration information based on the short PUCCH formatthrough cell-specific high layer signaling or UE-specific high layersignaling. In this case, each UE may set a priority per PUCCH format tobe used for transmitting any UCI. That is, a base station may set aPUCCH format having a high priority of the long PUCCH format and theshort PUCCH format for transmitting any UCI for each UE and transmitthrough UE-specific higher layer signaling or an L1/L2 control channel.Thus, in case a UE is configured to transmit any UCI through atime-domain unit (e.g., a subframe/slot/mini-slot), the UE may transmitthe UCI based on a PUCCH format configured with a higher priority forthe UCI. That is, in the time-domain unit (e.g., asubframe/slot/mini-slot), in case both an UL control region based on thelong PUCCH format and an UL control region based on the short PUCCHformat are configured, or only an UL control region based on a PUCCHformat having a high priority is configured, the UE may transmitcorresponding UCI based on the PUCCH format having the high prioritywhich is configured to transmit the UCI. In this case, in thetime-domain unit (e.g., a subframe/slot/mini-slot), in case only an ULcontrol region based on a PUCCH format having a second priority isconfigured, the UE may transmit the UCI based on the PUCCH format havingthe second priority.

As described above, each embodiment may be applicable alone, or any orall of each embodiment may be combined with any or all of one or moreother embodiments. In addition, the numerology described above isclassified based on a subcarrier spacing and a slot length. For example,the numerology may be classified into a numerology configured with a 15khz subcarrier spacing and a numerology configured with a 60 khzsubcarrier spacing. Further, the slot length may be changed depending onthe subcarrier spacing.

As described above, according to the present disclosure, it is possiblea UE and a base station to transmit and receive UL control informationwithout an error using a plurality of PUCCH formats set in the nextgeneration radio access network.

Hereinafter, structures of the UE and the base station for performing apart or all of each embodiment described above will be discussed withreference to the drawings.

FIG. 7 is a block diagram illustrating a UE according to embodiments ofthe present disclosure.

Referring to FIG. 7, the UE 700 may include a receiver 730 receiving atleast one of UL control channel resource set configuration informationand UL control channel transmission information from a base station, acontroller 710 configuring an UL control channel including UL controlinformation based on at least one of the UL control channel resource setconfiguration information and the UL control channel transmissioninformation, and a transmitter 720 transmitting the UL control channelto the base station.

For example, the UL control channel resource set configurationinformation may include at least one of i) UL control channeltransmission type setting information and ii) frequency resourceallocation information of the UL control channel. The UL control channeltransmission type setting information may include information on whetherfrequency hopping is performed for each UL control channel format, andthe UL control channel transmission type setting information may beclassified into a localized type and a distributed type. The localizedtransmission type means UL control information transmission through oneor more consecutive localized PRBs on which frequency hopping is notperformed. The distributed transmission type means UL controlinformation transmission through frequency hopping applied on a symbolor a symbol group basis. In addition, the frequency resource allocationinformation of the UL control channel may include at least one of ULcontrol channel format information and PRB allocation information foreach UL control channel format.

For another example, the UL control channel transmission information mayinclude at least one of UL control channel format information, ULcontrol channel transmission type information, and priority informationfor each UL control channel format, configured for each UE. The ULcontrol channel format information means information on a PUCCH formatincluding the long PUCCH and the short PUCCH. The UL control channeltransmission type information may mean information for indicating whichof the distributed type and the localized type is applied. Further, thepriority information for each UL control channel format meansinformation for determining a format having a top priority which can beused when a UE transmits the UL control information, in case both thelong PUCCH and the short PUCCH are configured for the UE. The UE maytransmit the UL control information using a PUCCH format having a toppriority.

Meanwhile, the UL control channel resource set configuration informationmay be received in advance for enabling the UE to transmit the ULcontrol channel. For example, the receiver 730 may receive the ULcontrol channel resource set configuration information through at leastone of cell-specific high layer signaling, UE-specific high layersignaling, and a common search space of a DL control channel.

The controller 710 may recognize radio resource information (e.g., PUCCHresource set information) for enabling the UE to transmit the UL controlinformation using the received UL control channel resource setconfiguration information. The UL control channel resource setconfiguration information may be configured cell-specifically andreceived by the UE.

The UL control channel transmission information may be received togetherwith or separately from the UL control channel resource setconfiguration information. The receiver 730 may receive the UL controlchannel transmission information through the UE-specific high layersignaling or the common search space of the DL control channel. That is,the UL control channel transmission information may be configuredUE-specifically and received by the UE.

Meanwhile, the controller 710 may configure an UL control channel fortransmitting the UL control information using the information.

For one example, the controller 710 may cause the UL control informationto be transmitted using a PUCCH format set for the UE in an allocated ULcontrol region.

For another example, in case of not allocating an UL control region foran UL control channel format configured for the UE, the controller 710may configure the UL control channel through an UL control region foranother UL control channel format having a resource index identical toan UL control channel resource index based on the set UL control channelformat. For example, an UL control region configured with four or moresymbols for transmitting the UL control channel using the long PUCCHformat may not be allocated even when the long PUCCH format is set forthe UE. In this case, the controller 710 may configure the UL controlchannel using an UL control region for the short PUCCH format which hasa resource index identical to an UL control channel resource index fortransmitting the UL control channel using the long PUCCH format.

For another example, the controller 710 may configure the UL controlchannel using an UL control channel format having a top priority basedon priority information for each UL control channel format. In case ofnot allocating an UL control region for the UL control channel formathaving the top priority, the UE may configure the UL control channelusing an UL control channel format having a second priority. Forexample, the controller 710 may determine an UL control channel formatand configure the UL control channel depending on a priority set for theUE using priority information for each UL control channel format.

Meanwhile, as described above, the UL control channel may be classifiedinto one or more formats based on the number of symbols contained in theUL control channel, as one criterion. For one example, each of an ULcontrol channel configured with one symbol or two symbols and an ULcontrol channel configured with four or more symbols may be configuredwith a different format from the other. For another example, an ULcontrol channel format may be classified into based on a payload size ofUL control information, as another criterion. That is, the UL controlchannel format may include a format configured with two or less ULcontrol channel transmission symbols and a format configured with fouror more UL control channel transmission symbols, transmitted through asingle slot, or may be classified into based on a payload size of ULcontrol information.

In addition, the controller 710 is configured to control the overalloperations of the UE 700 for transmitting UCI using a plurality of PUCCHformats in the NR according to the embodiments of the present disclosuredescribed above.

The UL control channel transmission typesetting information may include information on whether frequency hoppingis performed for each UL control channel format, and the UL controlchannel transmission type setting information may be classified into alocalized type and a distributed type. The localized transmission typemeans UL control information transmission through one or moreconsecutive localized PRBs on which frequency hopping is not performed.The distributed transmission type means UL control informationtransmission through frequency hopping applied on a symbol or a symbolgroup basis. In addition, the frequency resource allocation informationof the UL control channel may include at least one of UL control channelformat information and PRB allocation information for each UL controlchannel format.

For another example, the UL control channel transmission information mayinclude at least one of UL control channel format information, ULcontrol channel transmission type information, and priority informationfor each UL control channel format, configured for each UE. The ULcontrol channel format information means information on a PUCCH formatincluding the long PUCCH and the short PUCCH.

The UE maytransmit UL control information using a PUCCH format having a toppriority.

The transmitter 820 may transmit the configured informationcell-specifically or UE-specifically to the UE. For one example,transmitter 820 may transmit the UL control channel resource setconfiguration information in advance for enabling the UE to transmit theUL control channel. For example, the transmitter 820 may transmit the ULcontrol channel resource set configuration information through at leastone of cell-specific high layer signaling, UE-specific high layersignaling, and a common search space of a DL control channel. Thetransmitter 820 may configure cell-specifically the UL control channelresource set configuration information and transmit it to the UE. Foranother example, the transmitter 820 may transmit the UL control channeltransmission information together with or separately from the UL controlchannel resource set configuration information.
